Sword plants

Sword plants are large rosette plants that root deep and make a centerpiece or a full background, with the Amazon sword the most common. They are heavy root feeders, so root tabs in the substrate matter more than dosing the water. Each profile lists final size, light and placement, since a full-grown sword can fill a small tank.

The swords to start with

The amazon sword is the sword everyone knows, marked easy for medium light at 19.7 inches (50 cm), a rooted centerpiece for the back of a tank. The ozelot sword is spotted with red-brown, marked easy at 15.7 inches (40 cm). The red rubin sword grows red-brown new leaves at 19.7 inches (50 cm). The melon sword has broad, round leaves at the same height. The pygmy chain sword is the carpet of the family, marked easy at 3.9 inches (10 cm), spreading by runners. The Vesuvius sword grows narrow, twisted leaves at 11.8 inches (30 cm) for the midground.

The rule

What a sword needs

A sword feeds through its roots, so it wants a root tab pushed under it every couple of months or a nutrient substrate; a sword in bare gravel with liquid fertilizer starves slowly. About half the swords here reach 15.7 to 23.6 inches (40 to 60 cm) and spread 5.9 to 15.7 inches (15 to 40 cm). Those split about evenly between background and midground plants. A sword sold in a pot was grown out of water, and its first leaves melt in the tank while the submersed ones come; the plant is fine. A settled sword usually makes plantlets that root when pressed into the substrate, and a few, such as the chain swords, spread by runners.

FAQ

Common questions

Why are my new sword's leaves melting?

The pot was grown out of water, and the emersed leaves cannot live submersed. They die back over a few weeks while narrower submersed leaves grow from the crown. Cut off the dead ones and leave the crown.

Do sword plants need CO2?

No. Most swords here list it as beneficial, and none list it as required. The amazon sword lists no CO2 and grows to full size on a root tab and medium light.

How big does an amazon sword get?

The amazon sword grows 19.7 inches (50 cm) tall and 15.7 inches (40 cm) across, which is why it lists as a background plant. The quadricostatus chain sword at 5.9 inches (15 cm) and Echinodorus horizontalis Mini at 7.9 inches (20 cm) suit a smaller tank. The Hadi Red Pearl sword and the Ozelot Narrow Mini sword stay at 9.8 inches (25 cm).

What do swords need to grow?

Root feeding. A root tab pushed under the crown every couple of months, or a nutrient substrate, plus medium light. A sword in bare gravel with only liquid fertilizer yellows and stalls.

How do I propagate a sword?

Wait for the plantlets. Most settled swords send out a flower stalk or runner with plantlets along it. Press them into the substrate until they root, then cut them free. The Echinodorus Red Wild Grass spreads by side rosettes instead, which you cut away and replant.

Can a sword grow in low light?

The Reni sword, the Rose sword, the quadricostatus chain sword and Echinodorus horizontalis Mini list low light. The oriental sword, the Aflame sword, the Horemanii sword and the Paul Kloecker sword list high light. The rest list medium light and stretch without it.
